Product Overview
The ATS11057 air filter element is a genuine Ingersoll Rand intake filter element engineered for ATS series oil-free centrifugal compressors. Built with micro-fiberglass media, it delivers 99.97% filtration efficiency at 2.0 μm, blocking dust and particulate from entering the core compression chamber, protecting precision impellers and diffusers from wear, and supporting ISO 8573-1 Class 0 oil-free air quality.
As an OEM part within the Ingersoll Rand CC (Centrifugal Compressor) product line, P266 product group, the ATS11057 is manufactured to Ingersoll Rand global technical standards. Its three core advantages — low initial pressure drop, high dust-holding capacity, and long service life — help operators cut energy consumption and reduce unplanned downtime.

The ATS11057 uses micro-fiberglass media with 99.97% efficiency at 2.0 μm and above — well beyond standard screw compressor air filters (F5 class, 98% @ 5 μm) — meeting the stringent intake cleanliness demands of centrifugal compressors.
Flow and Pressure Drop
| Parameter | Value |
|---|---|
| Rated Airflow | Approx. 17–32 Nm³/min (for 110 kW class centrifugal units) |
| Initial Pressure Drop | Approx. 120–180 Pa (clean condition, rated airflow) |
| Operating Differential Range | 180–600 Pa |
| Alarm / Terminal Resistance | Alarm: 750 Pa; terminal: 1000 Pa (must replace) |
| Pressure Drop vs. Energy | Each 100 Pa increase in intake loss raises compressor shaft power by approx. 0.35% |
Ingersoll Rand data indicates this intake filter series offers a clean pressure drop about 40% lower than comparable alternatives and 89% higher dust-holding capacity, reducing energy consumption and extending replacement intervals.

Standards
- ISO 5011: Inlet air cleaning equipment for internal combustion engines and compressors — performance testing (efficiency and dust capacity)
- ISO 16889: Hydraulic fluid power filters — determination of beta ratio
- ISO 29463 / EN 1822: High-efficiency air filters (HEPA and ULPA) — classification and testing
- GB/T 14295: Air filters
- GB/T 6165: Test methods for air filter performance (efficiency and resistance)
Maintenance and Installation
Replacement Intervals
- Standard conditions: every 8000 hours or 12 months (whichever comes first)
- High-dust conditions (mining, building materials, foundry, etc.): every 4000–6000 hours
- Replace immediately when the pressure differential alarm triggers (≥750 Pa)
Installation Steps
- Shut down and isolate power: Switch off the main compressor power, apply lockout/tagout (LOTO), and confirm the unit has fully stopped.
- Open the intake filter housing: Release the housing clamps or bolts and remove the cover.
- Remove the old element: Pull the old ATS11057 element straight up and check whether the gasket remains in the housing groove.
- Clean the housing interior: Wipe the housing inner wall and sealing surface with a clean cloth — no dust, oil, or foreign matter.
- Inspect the new element: Verify part number ATS11057 and check the media for damage and the gasket for deformation.
- Install the new element: Place it vertically into the housing center, ensuring the gasket seats evenly on the sealing surface without skewing.
- Reassemble the housing: Refit the cover and tighten bolts or clamps evenly for a gap-free seal.
- Start up and leak-check: Run the compressor, listen for air leaks at the intake filter, and confirm the differential gauge returns to normal (initial pressure drop should be 120–180 Pa).
FAQ
Q1: Which Ingersoll Rand compressors does the ATS11057 fit?
A: The ATS11057 is designed for Ingersoll Rand ATS series oil-free centrifugal compressors in the 110 kW class. If you are unsure about your model, provide the compressor serial number and we will match it precisely.
Q2: How is the ATS11057 different from a standard screw compressor air filter?
A: Centrifugal compressors demand far higher intake cleanliness than screw compressors. The ATS11057 uses H11 micro-fiberglass media (99.97% @ 2.0 μm), whereas standard screw compressor filters are only F5 class (98% @ 5 μm). Using a standard filter can cause dust buildup on centrifugal impellers, disrupt dynamic balance, and even lead to impeller wear and scrapping.
Q3: How do I know when to replace the air filter element?
A: Replace in three cases: (1) operating differential reaches the 750 Pa alarm value; (2) the 8000-hour or 12-month interval is reached; (3) visual inspection reveals media damage or a hardened, deformed gasket.
Q4: Is the ATS11057 a genuine OEM part?
A: The ATS11057 is a genuine Ingersoll Rand part manufactured to Ingersoll Rand global technical standards and designed to fit genuine Ingersoll Rand intake filter housings.
Q5: What is the lead time for the ATS11057?
A: The ATS11057 is a long-lead order part with a standard lead time of approximately 110 days. We recommend planning purchases in advance to avoid impacting unit operation.
